There’s a scene in “Joe Dirt 2: Beautiful Loser” where David Spade’s title character gets farted on. A lot.

While this could be seen as an example of the juvenilia Spade and cohorts like Adam Sandler have remained mired in from early “Saturday Night Live” stardom through middle age, it’s also a stealth example of Spade branching out.

“For once, I wasn’t being snarky or sarcastic. I was . . . an everyman who was having trouble, and just trying to be a good person,” Spade says of the title character of the film, which debuts on Crackle Thursday.

It’s the sequel to 2001’s “Joe Dirt,” about a mulleted loser who — in an apt metaphor for the film itself — becomes a sympathetic hero during his search for his birth parents. Despite the movie’s poor reviews and weak box office ($27 million domestic), years of basic cable runs secured an audience who found Dirt endearing.

“It would . . . trend on Twitter, and I’d go, ‘My God, it’s still out there,’ ” says Spade. “I thought, maybe we should do something about this.”

Spade even had celebrity fans who offered to help fund a sequel.

“I ran into [Ultimate Fighting Championship president] Dana White years ago. He’s one of the guys saying, ‘Why isn’t there a “Joe Dirt 2”? I can get you the money in two days if you want,’ ” says Spade.

“Even Kid Rock [who appeared in the original], at one point, said, ‘I’ll put in a few million.’ ”

You fight your way on ‘SNL’ to get a voice, and once you get it, you fight your way to not do it anymore.

Returning cast members include Christopher Walken, who was eager to revisit his ex-mob-boss character.

The affection fans and cast members have for the film makes it easier, Spade says, to return to forms of humor you’d think a 50-year-old had outgrown.

During his 1990-1996 “SNL” stint, Spade became the king of snark with segments such as his celeb-skewering “Hollywood Minute.” Since then, he’s found success — as with his CBS sitcom “Rules of Engagement” — with essentially the same character, a horndog who’s quick with a quip.

Spade says he’d love to play different types of roles, but snarky single horndogs are all he’s offered.

“I’m down in such a specific category, it’s like a fetish . . . They come to me for comedy, sarcastic one-liners, wry, said under your breath,” he says. “You fight your way on ‘SNL’ to get a voice, and once you get it, you fight your way to not do it anymore.”

“I’m not trying to be De Niro here. It’s just . . . ‘Let [my character] be married, or have a girlfriend.’ I don’t even have those moves. So ‘Joe Dirt,’ yeah, I was happy to do that.”
